Mondays and Saturdays. (Also, Sundays in Advent, if you like.)
Tuesdays and Fridays. (Also, Sundays in Lent.)
Wednesdays. (Also, Sundays in Ordinary Time.)
(Or you can just ignore all the complicated instructions, and say the Glorious Mysteries on all Sundays, which is what we've always done around here.)
There are also some nice full recordings of the Scriptural Rosary by other folks elsewhere on the site, if you search for 'rosary'.
